Um, yeah, I just noticed the problem with that patch: half of the numbers
in that table are 33 bits, and cause a pile of warnings (not errors,
unfortunately!) from gas that scrolled by when I wasn't looking.

Logically, there should be no need for 33-bit values; they should all be
reducible modulo the polynomial. But that is going to take a slightly
larger change.
